2 Models Available:
Standard Digital O-Ring Test System
OTG-DG-T: Digital O-Ring Test System with Adjustable Measurement Timer

The Digital Complete O-Ring Hardness Kit is the most convenient and accurate way to perform repeatable hardness (durometer) testing on thin materials - as thin as .030"*.

The OTK-DG is comprised of the following items:
Model RX-DD-M - Type M Digital Durometer with Certification
ORF-1 - O-Ring Fixture Kit (1/16, 3/32, 1/8, 3/16, 1/4)
Model OS-3 - Air Dampened Operating Stand
TBKC-M - Test Block Kit with Certification

*Although the ASTM specifies that Type M Durometers can be used to measure O-Ring diameters as thin as 0.050" (1.25 mm), this system works well to 0.030" (0.75 mm)

OTG-DG-T - Adjustable Measurement Timer with Onscreen Countdown

The OTG-DG-T features an adjustable measurement timer with onscreen countdown designed for performing timed hardness testing. The timer can be set to a desired elapsed time from 0-30 seconds. When enabled, the timer function will be automatically activated when the presser foot meets the test specimen. Up to 200 readings can be stored and viewed inside the durometer or downloaded through the USB port.
